WEATHER-STRIP.

Specification of Letters Patent.

Patented Nov. 21, 1905.-

Application filed November 22,1904. Serial No. 233,826.

To all whom it may concern.-

Be it known that I, CHARLEs C. BOWERS, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented new and useful Improvements in Weather-Strips, of which the following is a specification.

My invention relates to weather-strips, and

more particularly a metallic strip to be apvention will be apparent from the detailed description hereinafter, reference being had to the accompanying drawings, in which Figure 1 is a vertical section of a window fitted with my Weather-strips. Fig. 2 is a horizontal section thereof. Fig. 8 is a perspective view of the two members composing the strips, showing the same separated. Fig. 4 is a perspective view of another form of one of the members.

Referring specifically to the drawings, 5 denotes the sill, 6 the jambs, and 7 the head, of a window-frame. The jambs have the usual parting-strips 8 and stops 9. The sashes fit and slide in this frame, the meeting-rail of the upper sash being indicated at 10 and that of the lower sash at 11.

The weather-strip comprises two members which are secured to the window and operate in the manner hereinafter described. They are formed of strips ofsuitable sheet metal corresponding in length to the height and width of the parts to which they are secured. The member or strip 12 has at one edge a flange 13, whereby it is secured, and along the other edge the strip is bent laterally and recurved to form a resilient socket 14. This socket receives a bead 19, formed along one edge of the other strip 15, which has a securing-flange 16 along the other edge thereof.

The space between the side walls of the socket 14'is narrowest near the mouth or opening thereofthat is, near the mouth the walls are bent inwardly, as at 17, to form a narrow passage, beyond which they are flared, as at 18, to facilitate the entry of the bead therebe tween. The head 19 is formed by bending the edge of the strip laterally and recurving the same to a contour corresponding to that of the socket 14, so that when the bead enters the socket it fits closely therein and contacts with thewalls thereof over substantially their entire surface, as shownin the sectional views, forming a broad and practically air -tight joint, a tight contact being assured by the resiliency of the parts.

In the form of the bead-strip 15, as shown in Fig. 4, the strip has two attachingflanges 16 and 16, one on each side of the bead 19. In use these flanges may be placed at any desired angle with each other to fit the parts to which they are attached.

In use at meeting-rails or wherever parts meet and separate the member 12 is secured to the meeting-rail ll of the lower sash and receives the head of the member 15, which is fastened to the meeting-rail 10 of the upper sash, the parts coming together, as heretofore described, when both sashes are closed. For use at a sill the member is fastened to the sill, and its bead enters the socket of the member 12, which is secured at the bottom edge of the lower sash. The use at the head of the window-frame is similar, except that the bead member 15 is attached to the sash and the socket member 12 to the frame, the head of which is grooved. For use between sliding members, as between the sides of a window frame and sash, the sides of the sashes are fitted with the member 12, their cooperating member 15 being secured to the parting-strips.

By the employment of these strips in the manner described cold air, dust, &c., will effectively be prevented from entering the room. The sashes will also work smoothly and are prevented from rattling or sticking in the frame.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination with parts of a structure movable to and from each other, of a me tallic strip secured to one of said parts, one edge of which strip is bent laterally and recurved to form a resilient socket having a narrowed opening, and another metallic strip secured to the other of said parts, one edge of which strip is bent and recurved to form a bead having the same shape as the socket and adapted to spring into and out of the same.

2. The combination with a window-frame and sliding sashes therein, of strips secured to opposite sides of the parting bead of the frame, and having resilient sockets formed by recurving the same along one edge thereof, said sockets extending beside each other along the front edge of the head, and a strip secured to and extending along the sash-stile of each sash, and having a bead fitting and slidable lengthwise in one of said sockets.

In testimony WhereofI have signed my name to this specification in the presence of two subscribing witnesses.
